MSI GTX 570 Twin Frozr III POWER Edition Thread - Page 60

post #591 of 1243
Mine stay fairly cool on my Lightning (57C @1.12v) but then again I do have more phases to spread the heat out across.

On the TFIII you only have a sheet of metal on them VS the DCII that have a HeatSink. And the TFIII spread the heat of its VRMs on the memory chips ....

In the long run, i dont thrust that much the TFIII. VRMs got damn hot on fermi.

This is your GPU temp, not the VRMs. VRMs are hotter than the GPU on MOST fermi cards.

Ok, you can either accept the information I gave to help you or assume that I don't know what I'm talking about, up to you.

@juano
Im far from telling that what you said isnt correct. Im just saying that VRMs are important on most fermi cards.
post #595 of 1243
I know VRM temps are important that's why I told you what mine run at with a similar cooling method (albeit different amount of phases as I mentioned) so you could maybe make a guess as to what yours run at.

Your GTX580 lightning is far from a GTX570 TFIII. Your have nearly twice the amount of phase and the plate that covers it is a lil different too.

Well, im not there to arg with you ........ BUT ....
post #597 of 1243
How many times did I mention the different number of phases? The cooling plate is functionally the same.

But yea you're right I'm not here to argue either. Here's a better way of saying what I tried to say to prevent an argument in the first place "take my info or leave it but don't tell me I'm wrong when you can't possibly know that". Because me saying "these are my VRM temps" then you saying "those are not your VRM temps" is telling me I'm wrong without having a clue what you're talking about. Assumptions and all that...

Your right, but theres a world between these cards wink.gif
post #599 of 1243
There we go, theres the magic words I was looking for. biggrin.gif

Now you'll find me to be much more agreeable, me offering info to try and help you and then being told I'm wrong is pretty annoying.

Yea you're right the cards are pretty different but not so much as that you can't compare them at all. The phases are the biggest difference in my mind, the cooling plates are quite similar IMO. Anyway yes you can't directly compare my number to what you might see, but my VRM temps at 1.12v are about 10C cooler than my core temps. So while this is just a guesstimate I wouldn't expect the 570 PE/OC TFIII's VRMs to be considerably hotter than it's core, I would guess they would be pretty close to the core temp at reasonable fan speeds (large increases in fan speed would of course cool the core more than the VRMs).

If you're wondering MSI AB does report the VRM and memory temps for 580 Lightnings, so that's where I'm getting my numbers.

actually PWM isn't covered with that metal, check those grey blocks sticking out next to capacitors

(scroll down a bit)

Imo its allot better then default:)
